Title: Image forming device
Inventor: YAMAZAKI KOJI
IPC: G03G21/08
Filed: 1988-01-28
Abstract: PURPOSE:To satisfactorily eliminate a ghost caused by a memory of an amorphous silicon (alpha-Si) photosensitive body even when a process speed is high by executing a destaticization by a prescribed wavelength light exposure on the upstream and the downstream sides, respectively of a cleaning device of the alpha-Si photosensitive body. CONSTITUTION:An alpha-Si photosensitive body 1 is exposed by a long wavelength light which is apt to generate a carrier with high efficiency in the inside of the photosensitive body 1 of >=660nm by the first destaticizing and exposing device 10 of the upstream side of a cleaning mechanism 11 after an image has been transferred and receives efficiently an optical memory erasing action. In this case, even if the destaticizing device 10 is on the upstream side of the mechanism 11 and a distance between the destaticizing device 10 and a uniform electrification main electrifier 2 becomes large and the photosensitive body 1 is turning at a high speed, its memory is erased satisfactorily. Subsequently, the photosensitive body 1 is exposed by a wavelength light of <=660nm by the second destaticizing device 12 of the downstream side of the mechanism 11 and its surface becomes a clean surface being uniform not only physically but also electrically. In such a way, even when an image forming process speed is high, a ghost caused by a memory of the alpha-Si photosensitive body can be eliminated satisfactorily.
